In Postgres 15+, NULLS NOT DISTINCT is supported so that a null value in
the same column is seen as the same value. This is not standard SQL and
Postgres 15 is likely too new to require. This is a workaround to
include partial indexes when some null values are provided.
Note that the first commit helps debug in a test/dev environment.
